5. C modeling#
5.1. Characteristics of modeling#
To avoid rigid body movements, it is mandatory that the movements \(\mathrm{DY}\) of the points \(\mathrm{A1}\) (belonging to the blank) and \(\mathrm{A2}\) (belonging to the punch) be identical.
5.2. Characteristics of the mesh#
Number of knots: 230
Number of stitches: 291 stitches (163 QUAD4, 12 TRIA3 and 116 SEG2)

5.4. notes#
The law of behavior of the material constituting the sheet is given in linearized form.
The calculation no longer converges beyond 75% of the total load.
